PAPER-BAG-DELIVERY MACHINE.

Application filed April 22,

Specification of Letters Patent.

Patented Mar. 5, 1912.

1911. Serial No. 622,726.

a citizen of the United States, residing at- Springwood, in the county of Botetourt and State of Virginia, have invented a new and useful Paper-Bag-Delivery Machine, of

whereby the carrier may be manipulated.

which the following is a specification.

The device forming the subject matter of this application, is a machine adapted to de' liver one bag at a time from a bundle of bags, so that the said bag may readily be grasped and removed.

A further object of the invention is to provide novel means for securing a reciprocation of the bag-carrier; to provide novel means for advancing one bag ata time, from the remaining bags, and to provide novel means for disposing the said advancing means, alternately, in operative and inoperative positions with respect to the bags.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,Figure 1 shows the invention in perspective; Fig. .2 is a fragmental vertical, longitudinal section; and Fig. 3 is a perspective of the bag-carrier, together with the adjacent coiiperating parts.

In carrying out the invention, there is provided, as a primary element, a supporting structure, preferably taking the form of a case 1, having, when desired, an open, slanting front face. The case 1 includes side walls 2 and a bottom 3. Across the rear edges of the side walls may extend a bar 4, to which is secured the upper sections 5 of the back of the case, the lower section 6 of the back of the case being hingedly connected to the case, adjacent the lower end of the case. These closure members denoted by the numerals 5 and 6, may be multiplied to any desired extent, depending upon the height of the case.

Located within the case 1, are a plurality of supporting members, upon which the carriers, hereinafter described, are adapted to slide. These supporting members may be of any desired form. In the present instance, I have shown them in the form of shelves 7.

Mounted for sliding movement upon each of the shelves 7, is a bag-carrier 8. Each bag-carrier 8 may be equipped at its forward end, with a suitable finger piece 9,

Upstanding from the carrier 8, adjacent the rear end thereof, is a pin 10, adapted to extend through the bags 11 which are superposed upon the carrier 8. Resting upon the bags 11 is a protecting member, the same preferably taking the form of a plate 12, having an opening adapted to receive the pin 10.

The plate 12 may be held in place upon the bags 11 in any desired manner. In the present instance, I have retained the plate 12 by means of a spring 22, which may be of any form. In the drawings, however, the spring 22 comprises an upright standard 23, which is rotatably mounted in the carrier 8, the standard 23 being formed, at its upper end, into a coil 24, the same bein prolonged to form an arm 25, extended longitudinally of the carrier 8, the arm 25 terminating at its free extremity, in a laterally extended finger 26, adapted to bear against the upper face of the plate 12.

Secured to the closures 5 and 6, are a plurality of arms 14, these arms being resiliout, and one arm being provided for each of the carriers 8. Each arm terminates in a transverse head 15, the resiliency of the arm 14, when the member whereby the arm is carried, is in closed position, serving to maintain the head 15 in contact with the plate 12. The construction is such, as will be described hereinafter, that the head 15 is adapted to engage with the fold 16 at the bottom of the uppermost bag 12, to advance the same beyond the other bags, when the carrier 8 is slid.

A means is provided for holding the 010- sure members 5 and 6 against the case 1, .so that the bag-actuating members 14 will be disposed in operative relation with respect to the bags. The locking devices above referred to, may consist of casings 17, secured to the side walls 2, the casing 17 having bayonet slots 18. Rods 19 are pivoted, as shown at 20, to the edges of the closures 5 and 6, the forward ends of the rods 19 extending within the casings 17. At their sure. This means for advancing the carrier 8, may be of any form. In the present instance, a movable member 27 rests upon each of the shelves 7. To this movable member 27 is secured the rear end of a retractile spring 28, the forward end of which is secured, as shown at 29, to the shelf 7 each carrier 8 being preferably an openbottomed structure, within the contour of which, the spring 28 is housed. Secured to each shelf 7, and upstanding from the same, adjacent the rear of the case, is a stop 50.

It will be seen that the several carriers 8 are graduated in length, and, if desired, in width also, so as to accommodate bags of different dimensions, the rearwardly slant ing front of the case 1, permitting a ready access to the bags which are upon the several carriers.

Presupposing that the parts are positioned as shown in Figs. 1 and 2, the operation of the device is as follows. The size of the bag desired having been determined, the carrier 8, provided with that particular size of bag, is pushed rearwardly, manually, putting the spring 28 under tension, the stop 50 serving to prevent an undue rearward movement of the carrier 8. When the carrier 8 is thus moved rearwardly in the case 1, the head 15 upon the end of the arm 14, slides from the plate 12, and engages beneath the fold 16 of the uppermost bag 11, thus advancing this bag beyond the other bags, the last named bags being held in place by their engagement with the pin 10. When manual pressure is removed from the carrier 8, the spring 28 will advance the movable member 27 removable member 27 in its turn, advancing thecarrier 8 to the front of the case 1, so that the bag which has been manipulated by the head 15 of the spring arm 14, will protrude beyond the case, as denoted by the letter B, in Fig. 2. This bag may readily be plucked from beneath the plate 12. Stops are provided at the front of the case to limit the movement of the carriers 8.

When it is desired to supply one of the carriers 8 with bags, the rods 19 are manipulated, out of locking engagement with the casings 17, one of the closure members 5 or 6, as may be, being tilted rearwardly into open position, as shown in dotted line in Fig. 2. This operation will raise the free end of the spring arm 14, lifting the head 15 off the.

plate 12, whereupon the carrier 8 may be drawn forwardly out of the case 1. The spring 22 may be rotated, laterally, so that it no longer presses upon the plate 12, whereupon the plate 12 may be lifted off the pin 10, a new supply of bags being placed upon the pin10, the plate 12 being replaced, and the spring 22 being rotated, laterally, to bear again upon the plate 12. The carrier 8 may then be inserted into the case 1, whereupon the member -5 or 6 is tilted into closed position, so that the spring arm 14 again presses its head 15 upon the plate 12. I

The plate 12 serves, among other functions, to prevent the head 15 from drawing back the upper bag, after the latter has been advanced as shown at B in Fig. 2.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a supporting structure; a bag-carrier slidable in a fixed plane thereon; yieldable means for moving the carrier in one direction; and a bag-engaging element held fixedly above the carrier, and adapted to engage in the fold of the uppermost bag on the carrier.
